Anyone have any recommendations for the best type of sealer to use (or avoid) or other must-do items to fix leaky gutters? I recently discovered that water was coming into the interior up around the gutters, and while I initially thought it might be just a few rust pinholes, it didn't take more than a few seconds up on the ladder to see what the problem was. Of course, on a less-tall vehicle, I might have spotted it sooner. Several of the spot welds appear to have rusted through and/or separated. Water is coming in through the gap between the two layers of sheet metal. Plenty of dirt and even a little bit of moss. See photo... It's depressing. Of course, the right thing to do is to strip it down to bare metal and weld it, but that is not in the cards. You'd have to remove the entire roof to get the rust out in between. My tentative plan is to clean out the gutters as best I can (water, toothbrush, air gun, wire brush, maybe even a pressure washer) and then apply a seam sealer. I'm leaning towards "Dynatron 550" but open to suggestion of other products, prep/application tips, etc. Ideally I'd like something that I can really force into the gap, similar in thickness to Bondo or household painter's caulk (though I understand I can't use house caulk). Self-leveling would presumably run to the end of the gutters and out, so that's no good. The sealer needs to stick to paint and to bare metal and hopefully to dirty/rusty metal too. Needs to be paintable and sun-stable. Doesn't have to look great because you'd have to be 9 feet tall to see it.
